SUPPORT' AND TIE Fon ooNcRinTE-nniivroncnve.

Vfor concrete reinforcing and seeks toprovide a simple and effective form of support and tie which Ina-y be made in various sizes to suit the different forms of reinforcing and readily applied thereto.

Reinforcing is used in most forms of concrete and must be bound together and held in place while the concrete is poured into the mold or form. It is essential that some -form of tie be used that will rigidly hold the reinforcing together, and where floors, roofs, walls and the like are to be poured, the reinforcing must be held above the bottom, or away from the side of the mold into which the concrete is to be poured, so that the reinforcing will be embedded at a sufficient depth in the concrete to reinforce it. The present invention seeks to provide a support and tie that will rigidly hold the reinforcing together in any position either in parallel or cross connections; and to support and hold the reinforcing away from the bottom, or side of a mold or form while the concrete is poured, so that the reinforcino' will be embedded in the concrete to a suicient depth to reinforce the concrete.

lVith these and other objects in view, the invention consists in the features of construction, shapes, combinations and arrange ments of parts hereinafter set fort-h, illustrated in the drawings and more particularly pointed out in the claims appended.

In the drawings: Figure 1 is a perspective view of the improved reinforcing support and tie. Fig. 2 is an elevation of Fig. 1 illustrating the application to a pair of reinforcing rods which cross each other at approximately right angles. Fig. 3 is an elevation of Fig. 2 at an angle of 90 degrees, and with the reinforcing rods omitted. Fig. 4 is the same view as Fig. 2, but with the reinforcing rods approximately parat lel. Figs. 1, 2, 3 and 4 are enlarged views. Fig. 5 is a section of concrete illustrating Specification of Letters Patent.

serial No. 661,654.

single piece of sheet metal and formed of a double body portion 1 1 which is joined` together at 6 and terminates in the supporting end 2, the opposite terminals being bent preferably in the form of an arc at 3 to form arms 4 5 which represent an angle of less than 90 degrees from the body portion at 4 and a greater angle than 90 degrees at 5.

The arm T-S is bent so that 6 7 forms approximately a right angle to the body 1 1 2, while the corners 8 8 are turned to form a concave surface at 7 S 8 on the side next to arms 4 5.

The arm 4 5 at 10 is closer to arm 6 7-8 than at 3 and it is obvious that if a body, as 11 and 12, be pressed beyond this point toward the body portion 1 1 that the arms will grip and hold the same in Igid position.

In Fig. 2 the reinforcing rods 11 and 12 are held at approximately right angles to each other, while in Fig. 4 the rods are approximately parallel. The curvature of 7 8-8 holds the rod 12 at an approximately right angle to the body 1 1 2, while the angles 6 8 enables the tie to hold the rods 11 and 12 as indicated in Fig. 4. The arms 4 5 are also closer to arms 6 7 at 10 than at 4 which aids in holding the rods 11 and 12 when once pressed past the point 10. The support and tie is made of an elastic metal to allow the arms 4 5 and 6 7 to spread apart when applying the tie and this aids in securing a rigid'grip when applied.

The supporting ends 2 hold the reinforcing rods 11 and 12 from coming in contact with the mold, as indicated at 2 2, Fig. 5 and positively spaces them in the concrete to a suiiicient depth to insure the reinforcement of the concrete.

At 14 and 15 the support and tie is used only as a tie to bind the rods of different sections together.

The corners 9 are angularly shaped to allow the reinforcing rod 11 to be more easily pressed into place beyond the point indicated at 10. This allows first one arm of the tie to be pressed over the rod and then the other, the angle allo-wing the second arm to more easily slip over the rod.

The support and tie is of chief importance in connection with reinforcing rods in concrete floors, roofs and the like, but may be advantageously employed in connection with reinforcing rods for walls, piers, abutments, arches and the like.

It is obvious that numerous changes may be made in the details, as set forth, withoutl departure from the essentials of the invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

l. In a concrete reinforcing support and tie forV securing pairs of rods together, a divided body portion, a supporting portion connect-ing said body portion and lying in the plane thereof, the metal from between said divided body portions bent to form an arm, said arm extending at an approximate right angle to said plane, the extremities of said divided portion bent to form arms, said arms extending outward from said plane, said arm and said arms being closer together at their extremities than at-a point near the body portion.

2. A concrete reinforcing support and tie for securing together pairs of transverse rods and pairs of parallel rods comprising, divided body portions, said divided portions joined at one end by an intersecting portion, said intersecting portion extending from said divided portions in the plane thereof and forming a supporting portion, an arm extending from said supporting portion and from between said divided portions, said arm forming an approximate right angle to the plane of said body portions and said supporting portion, and arms formed on the opposite end of said divided portions, said arms inclined. toward said armV and then away from said arm.

In testimony whereof I atiix my signature in the presence of two witnesses.
